F HOLLAND, MICHIGAN n RESILIEN'I CUSHION Application led April 18,

This invention relates to resilient cushions.

An object of the invention is to provide a cushion made up of a plurality of coiled springs arranged in a plurality of parallel rows and wherein theindividual springs of each row are connected at their opposite sides to the springs in adjacent rows by simple means which prevent relative displacement of the individual springs with reference tol each other and said connecting means.

A more particular object of the invention is to provide a cushion wherein the opposite ends of each coiled spring are formed with rings having diametrically outwardly disposed oit-sets, with the terminal ends of the wires forming the spring disposed inwardly beneath the rings and also provided with an .ott-set in alignment with one of the off-sets of the ring, whereby the terminal ends co-opcrate with the rings to provide two thicknesses of material for co-operation with connecting means which secure the coiled springs together and aid in preventing relative movement of said coiled springs with respect tosaid connecting means.

Still another object of the invention is to provide a cushion of the character referred to in which the coiled springs are so arranged as to dispose the two thicknesses of wire at tion with reference to the single thickness of wire of a spring in an adj acent row, whereby three thicknesses of wire are presented at the points of the coiled springs engaged by the connecting means throughout the body portion of the cushion, and wherein each row forming the outside or border row of the cushion is formed by reversing the positions of the coiled springs so that the two thicknesses of wire are presented along the margin of the cushion, and the springs of the marginal row have their inner side comprising a single thickness, disposed adjacent the single thickness presented by the springs of the next row.

Other and further objects of the invention will more clearly and fully appear from the description and claims hereinafter following.

In the drawings forming a part oi this each end thereof of each spring in juxtaposi` 1927. serial No. 184,453.

specification, Figure 1 is a broken top, plan View of a cushion embodying my invention. And Figure 2 is an enlarged vertical sectional view taken-through the cushion substantially i upon the line 2-2 of Figure 1. v As shown in i 55 the drawings, 10 indicates an out-side or inarginal row of coiled springs, 11 indicates a row ot coiled springs disposed 4next to the marginal row 1Q, while 12 indicates a plurality of intermediate rows of springs, and 13 indi eo cares a marginal row disposed opposite the marginal row 10, as many intermediate rows 12 being provided as desired, depending upon the width of the cushion.

Each of the rows 10, 11, 12 and 13 is made et up ot a plurality ot coiled springs indicated at 14, arranged in spaced relation as shown, an"`d as many springs 14 may be included in the various rows as desired, depending upon the length ot' the cushion it is desired to conim struct. AllV of the coiled springs 14 are of exactly similar construction, but are arranged in a particular manner to provide an efficient type of cushion as hereinafter described.

Each of the coiled springs is made up ot 't5 resilient wire of suitable gauge, and comprises an intermediate body portion, the opposite sides ot which are concave as shown, the intermediate portion including a plurality of helical turns of wire indicated at l5, so while the top and bottom ends of dach coil are formed in circular rings or annuli 16 and 17 disposed substantially at right angles to the longitudinal axis of the coil, and the terminal ends of the wire are indicated at 18 and sa 19, each of the ends 18 and 19 being disposed inwardly of the ring members 16 and 17 as shown, so that the ends of the coil do not project outwardly of the plane defined by the rings 16 and '17. Each ot the rings 16 ee and 17 isprovided with diametrically disposed oit-sets 20 and 21, and the terminal ends 18 and 19, are provided with off-sets indicated at 2Q disposed inalignment with the oit-set 21 in each ring. The marginal row 95 1() of the cushion is made up of a Jlurality of the springs 14 of the character escribed with the two thicknesses of wire provided by one side of the ring, and the terminalend of the wire, disposedoutwardly as best shown 1Q@l at the right-hand portion of Figure 2, theref by presenting only a single thickness of wireinwardly toward the remainingrows of the lcushion. The lsprings of the row 11 are reversed so as to present a single'thickness of wire at the top and bottom of the coil in juxtaposition with reference to the single thickness presented by the rings of the marginal.. row 10, thereby presenting a double thickness of each spring of the row 11 inwardly.v The springs 14 which go to make i in juxtaposition` with reference to the double thickness presented by the coiled springs of y.the row 11, and each of the successive rows 12 are disposed in the same manner sogas to present three juxtapositioned thicknessesat the adjacent top and bottom ends of the springs forming 'the rows 12, until the opposite marginal row 13 is reached.` The s rings of the row 13 are oppositely dispose with reference to the springs of the marginal row 10, so as to resent two thickne'sses of the springs outwar ly, .while the'single thickness is dis-` posed inwardly in juxtaposition with reference to the single thickness of the next'intermediate row 12 of the-cushion.

Connecting members indicated. at 23, 24, 25, connect the various rows of coiled springs together at the top and bottom ends. Each of the connecting members comprises a small coiled Wire which at the outer side of the marginal row 10 istlgeaded through the ofsets 21 and 22 in the rhgs 16 and 17 and the terminal ends of the coil, as best shown in Figure 1, the connecting member serving to secure the various springs comprising the row 10 together, and securing the terminal ends of the spring in positions on the inner sides of the rings, the inter-engagement of the connecting members with the off-sets in the terminal ends and rings of the coiled springs preventing rotation of the springs with reference to the connecting members and preventing displacement of the springs. The

connectingmember 24 is of a character similar t the connecting member 23 and connects the off-sets 2O of the springs of the rows 10 h and 11, only two thicknesses of wire being disposed within the coils of the connecting member at this point, but the off-sets preventingrelative isplacement of the springs of the rows and 11. The connecting mem ber 25 is similar to the connecting member 24 and the Vcoils of the connecting member are interengaged with the off-sets 21--22 and 20 of the rows 11 and 12 of the springs, and by reason of the disposition of said springs, three thicknesses of wire are placed within the coils of the connecting member at the oints of connection of the springs comprising the rows 11 and 12. p The next successive `rows 12 will have the springs disposed in the same manner as the rows 11 and 12, and in each instance at the connecting points between the rings ,of the springs, three thicknesses of wire will be presented and engaged within the loops of the connecting members, providing an important advantage in eliminating any possibility of the coiled springs moving with reference to each other and t0 said connecting means. The opposite marginal row 13 is affixed to the last of the intermediate rows 12 in the same manner as the springs of the row 10, the two thicknesses being presented outwardly, while the single thicknesses of the springs forming the row 13 and the next intermediate row are secured together as before described.

By the above described arrangement it will be appreciated that due to the disposition of the terminal ends of the coils, said ends are held beneath the rings thereof when the connecting members are in position, and due to the formation of the off-sets in both the terminal ends of the springs and the rings, at all points in the cushion, except at the marginalr edges thereof` three thicknesses of material are embraced by the coils of the connecting member, absolutely preventing any possibility of relative displacement of the coiled springs withr'eference to each other and said connecting means, and additionally by reason of the reversal in position of the springs forming the marginalrows 10 and 13, two thicknesses of material are presented at the marginal edges of the cushion for inter-eii gagemen-t with the coils of the connecting members, thereby providing means for preventing relative displacement of the coiled springs of the marginal rows with reference to the connecting members.
